Randall: Thanks for responding. OK, I have looked at the stream functions: My question was, basically, how do I specify how many bytes I want to take in from a given serial port at each instance? For example, on one input I expect a continuous stream of 31 byte packets and I want to take them in for processing 25 (say) packets at a time, i.e. 775 bytes at a time. Now I don't much mind if I get a few bytes more or less because I can check for a remainder part-packet and put it on the front of the next nominal 775 byte intake - that's part of the processing software - but I don't want the CPU tied up with that port or stream between intakes of (about) 775 bytes. There are other input streams and data processing to attend to. I don't see how to do that with the stream functions - but maybe I'm not understanding how the stream works? I can see that I could (I think!) read a given number of bytes from a stream, but does that relieve the CPU from being tied up with that stream until I read another 775 bytes? Is a stream of indefinite length or does it have some buffer limit? Carl
